Issue #3247039 by joachim, quietone: MigrateDestinationInterface::import()...

   *   plugin's getIds() method if the plugin wants to save the IDs to the ID

   *   map, TRUE to indicate success without saving IDs to the ID map, or

   *   FALSE to indicate a failure.

   *

   * @throws \Drupal\migrate\MigrateException

   *   Throws an exception if there is a problem importing the row. By default,

   *   this causes the migration system to treat this row as having failed;

   *   however, any \Drupal\migrate\Plugin\MigrateIdMapInterface status constant

   *   can be set using the $status parameter of

   *   \Drupal\migrate\MigrateException, such as

   *   \Drupal\migrate\Plugin\MigrateIdMapInterface::STATUS_IGNORED.
